In the time since Kate Middleton had gone from Prince William's girlfriend to the Duchess of Cambridge to her newly-minted title as the Princess of Wales, the 41-year-old has cemented herself as one of the world's most stylish women.

As an ambassador of high street fashion and locally-grown British talent, the future queen consort is often likened to her late mother-in-law Princess Diana for her regal yet relatable style.

And while Kate's habit of re-wearing affordable basics has earned her praise from the public, that isn't to say the Duchess is lacking in glamour.

Whether visiting with dignitaries or attending the Royal Ascot, the 41-year-old Princess always comes dressed to impress. Therefore, who better than Kate Middleton to inspire our summer wedding wardrobes?

For garden weddings, cocktail receptions and everything in between, scroll down to shop 24 wedding guest dresses inspired by some of Kate Middleton's most iconic looks for the upcoming wedding season.
